I want to find a combination where I can use a usb passthrough and direct drip my VG juice. I have been using a smoketip passthrough with a 901 atty. It worked at first but now my atty gets really hot and starts smoking! 
The smoketip passthrough is 5volt, according to their website.
I need some advice on what set up I need to direct drip and vape with a passthrough.
Any suggestions???
